Rifle comprising a rear stock and a barrel removable from said rear stock

0001The present invention relates to a rifle, comprising a buttstock and a detachable from the buttstock run, the buttstock a having shaft housing, wherein the shaft has a cup-shaped, elongated Recording for the run shows, which run at least one pin and Corresponding to this, the cup-shaped receptacle has an opening for has receiving the pin.

0002A rifle, in which the overflow from the buttstock is releasable in the art known as the "take-down" rifle ". Such rifles, wherein where the term is to separate from the buttstock, especially result used when such a gun has to be transported, or when the run is to be replaceable.

0003A gun of the type mentioned by the company under the Blaser Designation R93 known. Here, the shank, in particular in the Region of the rear shaft, a shaft housing having chamber, said Housing comprises an elongate, cup-shaped receptacle for the run. in the Section of this elongated, shell-shaped receptacle are two bores provided. The run has to correspond to these holes two Pins that, through the corresponding holes in the elongate cupped you recorded. The pins have a Externally threaded, with the holes in the elongate cupped receiving through the shaft to continue throughout. to Fixing the barrel on the shaft, and in particular on the elongated, cupped receiving the shaft housing, are now nuts provided onto the threads of the pins by means of suitable tools can be screwed, thereby the barrel on the shaft housing, and therefore the fixing shank.

0004A disadvantage of this known gun that to run change always Tool is needed. In most cases this is a screwdriver or Allen key, which can easily be lost in the forest, or Contamination and damage to the thread unusable make, so that the weapon is not usable in such a case.

0005The invention is thus the object of a gun of the above mentioned type such that the drive installation without tools is or removed.

0006The object is achieved in that the at least one Pin at its free end a preferably circumferential groove, has said a locking device is provided, which cooperates with the groove. By actuation of the locking means of the running can be fixed on the shaft will.

0007Advantageous features and embodiments are in the dependent claims to remove.

0008So it is especially provided particularly advantageous that the least a pen in his over the barrel projecting length is variable, what advantageously thereby can take place in that the pin which by a thread with Running communicates. By changing the protruding length of the pin, and therefore of the distance of the groove from the running, there is always the Possibility to run substantially free of play to the shaft or the elongated connecting cup-shaped receptacle.

0009In detail further, it is provided that the locking device a component of the stock, or in particular a component of the is the stock housing, wherein the cup-shaped elongated receiving portion of the may stem housing. In particular, when the Locking device is an integral part of the shaft housing is achieved, that during the mounting of the barrel with the shaft to no Tension build between the components coming.

0010The locking device comprises specifically a slide plate, the slide plate advantageous for locking the at least one pin parallel to the longitudinal axis of the barrel in the shaft housing slidably is mounted. Locking is therefore by means of the slide plate, wherein it has found that such a type of interlocking between Pin and slide plate is quite robust.

0011In detail, the slide plate has at least one elongated opening, wherein the cross section of the opening for the positive detection of the groove of the Pin in a first region approximately to the residual cross-section of the pen in Region of the groove corresponds to, and in a second region in about the Cross-section of the pin, so that the course of at a first position Slide plate is locked, and in a second position of the slide plate the run from the shaft is removable.

0012To operate the slide plate in the shank housing is pivotable arranged lever provided, wherein the levers each advantageous in Offenund Closed position is fixed. To fix the lever that is of at least one side by a pressure piece is. The pressure element is as a formed in a sleeve bearing ball, which is spring loaded, wherein the Sleeve has a thread for receiving through the shaft housing. By Adjustment of the position of the sleeve in the shaft can thus the pressure force of the ball be varied on the lever.

0013Referring to the drawings, the invention is exemplified below in more detail explained.<dl tsize="8" compact="compact"><dt>figure 1</dt><dd>shows the rifle in an assembled state;</dd><dt>figure 2</dt><dd>shows the rifle with dissolved run and dissolved forearm;</dd><dt>3a</dt><dd>shows the detail "X" of Figure 2 in an enlarged view on average;</dd><dt>3b</dt><dd>shows the detail "X" of Figure 1 also in an enlarged Sectional representation;</dd><dt>figure 4</dt><dd>shows in perspective a view from below of the Shaft housing;</dd><dt>figure 5</dt><dd>shows a view along the line V - V of Figure 3a.</dd></dl>

0014According to Figures 1 and 2 shows the overall designated 1 gun a forearm 2, a buttstock 3 and a run 4. In the present Case make the running, the buttstock and forend three together represents connectable parts, but also an embodiment is conceivable in of the fore-end 2 and the rear shaft 3 are integrally formed.

0015The invention is now the fixation of the barrel 4 at the Buttstock 3. The designated overall by 3 buttstock has at its the front end, generally designated 10 shaft housing. To the then designated 10, shaft housing is located on the Buttstock elongated, shell-shaped receptacle 11 for the run 4. In Field of dish-shaped receptacle 11 for the run 4 are two openings 12 which finally the recording of the two pins 5 of the barrel 4 serve. The pins 5, which is adjustable by a thread 6 in height in the Run 4 can be screwed, have in the area of ​​the front end in each case a circumferential groove. 7

0016The shaft housing 10 has, moreover, the indicated at 20 Locking device on. The designated 20 locking device specifically includes a lever 21 and by the lever 21 parallel to Longitudinal axis of the barrel sliding slide plate 22. The slide plate 22 has two successively arranged elongate openings 23. The openings 23 show two portions 23a, 23b of different diameters. Of the Section 23a corresponds in its opening width to the diameter of the pin in Area of ​​its groove 7, whereas the portion 23b the pin diameter equivalent. The distance of the groove 7 on the outer diameter of the barrel corresponds approximately to the distance of the slide plate 22 from the top of cupped receptacle 11 so that the slide plate 22 with their area 23a are brought to locking in the region of the groove 7 of the pin can. It is clear that after the insertion of the barrel into the cup-shaped receptacle 11 when the pins 5, the opening 12 of the cupped receptacle 11 and the opening portions 23b of Slide plate 22 by project, by pivoting of the lever 21 in moving direction of the arrow 25, the slide plate in the direction of arrow 27 can be a result of which the opening portion 23a in the region of the groove 7 the pins reaches 5, and thus fixes the run on buttstock is how this seen from Figure 3b.

0017As particularly Figure 2 and Figure 3a removed, is a release of the Barrel 4 from the shaft 3 only possible with shutter 40 open. In this Position are retracted and the two parallel guide rails 41st After connecting the barrel 4 with the buttstock 3 of the closure may 40 are closed, which means that the guide rails 41 in the corresponding recesses along the barrel slide. These Guide rails 41 of the shutter 40 do not have the task of Fixing of the barrel, but are for the guidance of the barrel.

0018In order to prevent the lever 21 from the locked position according to 3a solves independently, are in the range of the lever side of the lever attacking plungers 30, said such a pressure piece 30 from a sleeve 31 is made, which has a spring-loaded ball 32nd Through this spring-loaded ball 32, the lever in its closed position and in its open position, respectively a recess for the spring-loaded ball 32 which is fixed.
